In order to assess pavement stiffness, non-destructive testing by means of deflection measurement was carried out;

·         DCP Test (7134 points)

DCP test was carried out to find CBR salve of the field using the relationship between CBR and DCP value;

·         Test Pit Inventory (7,134 points)

Test pit inventory was carried out to determine the layer thickness of road construction and type of materials used in construction below the surface;

·         Bridge and culvert condition Assessment (7,435 nos.)
